Carbureter.



and connected to the head 2 of the body l by screw bolts 29 or otherfastening means. The connection 28, as in the case of a manifoldconnection, contains the usual throttle or butteriiy valve 30.

Extending upwardly into the cap 25 is an annular wall 3l forming part ofthe head 2 and said Wall has air intake openings 32 adapted foradmitting air into the well 5 and the chamber formed by the Wall seat 3of thc he annular shutter 33 is inverted channel shaped in cross sectionand is Weighted or balanced, as at 34to normally close the air intakeopenings 32 of the Wall e annular shutter may be raised by a reductionof atmospheric pressure in the upper part of the cap 25, particularlybetween the Wall 31 and the annular Wall of said cap, and impetus may beimparted thereto by'a member to be hereinafter reicrred to.

side Walls thereof provided With openings 36. The top of the regulatingmember 35 has a concentric outlet sleeve 37 directly above the sprayYnozzle 22 and the inner Walls of this outletv sleeve are helicallygrooved to coperatie With the tangentially disposed grooves 24 of thespray nozzle 22 in imparting a whirling movement to air and liquid whenemitted by the sleeve 37'.

he upper end ofthe regulating member 35 normally rests on the spraynozzle 22 and coperates With said nozzle in providing a restrictionwhich may increased in area ber and fin proxsaid may be elevated toplace the openings 36 thereof in communication with the Well 5. Theupper large end of the foraminous member 39 corresponds in diameter tothe connection 28 and `iS Supresaca@ ported on the cap 25 at the edgesof the opening 2?'. The perforations or apertures of the member 39 maygradually decrease 1n diameter from the small end of the memhas ascrewthreaded portion 42 in engagement with a hanger 43 so that rotationof the rod 4-0 Will raise and lower said hanger 43. The hanger 43extends through one of the perforations or openings of the loramiA nousmember 39, and under normal conditions. has the lower end thereofloosely connected to the regulator member 35. The lovver end of thehanger, however,` has nuts te or other fastening means so that theregulator member 35 may the lower end of the hanger.

In operation, an initial reduction of atmospheric pressure in the Well 5pulls air and gasolene into 'the outlet sleeve 37 of the The n'xiXt-ureis directed toward the inner Walls ot the foraminous member 39 to bebroken up by air passing through the perforations or apertures of saidmember. The deiector il positively divides the discharge from the sleeve3'? and said delector may be adjusted to increase and decrease therestriction at the lower end of the foraminous member. Furthermore, thefirst suction impulse in the `Well 5 tends to raise the regulator member35 which Will increase the space for the outlet of air between thenozzle and the regulator member. As the regulator member is raised theopenings 36 thereoi' are graduallv brought into communication With theWeil 5, admitting air thereto so that the air may enter the lovvermostpcriorations or apertures for the ioraminous member and commingle withthe mixture passing through said member.

n account of the resilient arm 38 resting on the regulator member 35 almovement of the member 35 will impart sutcieut impetus to the auxiliaryvalve 33, to coperate with the'suction in the cap 25 in raising theauxiliary air valve, thus allowing air to enter the cap and break up themixture within the toraminous member at all sides thereof.

When it is desired to obtain a very lean mixture, the regulator member35 may be iixed relative to the hanger 43, so that by be fixed relativeto meses@ rotating the rod 40 the regulator member may be raised to adesired height to permit of a desired quantity of air passing throughthe openings 36 and between the nozzle 22 and the regulator member 35.By the outlet sleeve 37 moving to and from the deeetor il a restrictionmay be accomplished within the foraminous member, besides therestriction with Which thel spray nozzle 22 forms a part.

irrespective of how fuel or nir are admitted to the nozzle 22, members35 and 39, these elements constitute an outlet member that is applicableto various types of mixing devices, and While it is thought that theoperation and utility of the method ,of automatically regulating themixture of air and gasolene by the device will be apparent to thoseskilled in producin explosive miie tures, it is to be understoo that'thestructural elements disclosed in the drawing are susceptible to suchchanges in size, shape and manner of assemblage as fall Within the scopeoi? the appended claims.

'What il claim is l. An outlet member for a mixing device, comprising aspraying nozzle having a 'fuel inlet at the lower end thereof and theupper end thereof provided with tangentiall dis posed grooves, aninverted conical s aped foraninous member above said spray nozzle andsupported independent thereof, a regulator member on said spray nozzlehaving an interiorly grooved outlet sleeve extending into saidforaminous member adapted to cooperate with said spray nozzle inimparting awhirling movement to a mixture -liquid et injected into saidoreminous member, a de Hector in said oraniinous member, and aconnection between said deiieetor and said regulator member andextendingf through said oraininous member so that said re lator membermay be moved by said e- Hector.
